timesales-futures-demo.txt attached is a python demo to download some futures time/sales data. The example uses the polling described in your sample tutorial code. However, is there an alternative way to just post a bunch of requests, store the requestid, and then retrieve these results at a later time (e.g. skipping the pausing/polling step)? In the old version of tick history you could submit a bunch of requests. For each request you would get back a request id and then sometime later you could come back to request to download the requestid, provided it had finished populating. Can you describe how this works in the new service? i.e. there used to be ability to make multiple asynchronous calls.
